Safety Analysis of Continuous Green Through Lane Intersections

This paper examines safety characteristics of continuous green through lane (CGTL) intersections
using paired-t test and ordered probit (OP) statistical models. The results suggest that there is a
significant difference between the proportions of sideswipe crashes in the CGTL direction compared
with the opposite direction. However, the results did not suggest a significant difference between the
proportions of rear-end and right-angle crashes for the CGTL and normal directions. The results
further suggest that angle crashes and crashes involving lane changing maneuvers are significantly
more severe compared with rear-end crashes.
